IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 58,6l7. dated October 9, 1866.

To all whom it nay concern:

Be it known that I, JOSEPH DICK, Jr., of Canton, in the count-y of Stark and State of Ohio, have invented certain new and useful Improvements in Self-Baking Reapers; and I do hereby declare that the following is a full, clear, and ex act description thereof. reference being had to the accompanyingdrawin gs, ma king part of this specication, in which- Figure 1, Sheet B, is a top view or plan of the main frame, Src., of the Ball machine, eX- cept a portion of the platform P and of the rake-head M and of the reel, with my invention attached. Fig. 2, Sheet A, is a righthand-side elevation of the same, the platform and reel being removed. Fig. 4; is a righthand-side elevation of the divider-board D and wheel WV, showing theinclined axis of the caster-arm A. Fig. 3 is a rear elevation of the frame of the machine, showing the relative ar an gement and manner of connecting thereto the raker attachment, the ball-joint, reciprocating post j', with its arm D, and pinious G and C' being shown in vertical section. Fig. 5 is a transverse section of the pulley T and and sleeve S. Fig. (i is a detached face view Of the pulley T.

Similar letters indicate corresponding parts in all the figures.

The nature of this invention will be better' understood by reference to the drawings and specifications.

, The main portions of the Ball machine I use without reconstruction, though my invention can be applied equally well to many others.

The stock H, upon which the supports of the raker are fixed, is bolted to the Cutter-bar R. To this plate are bolted two standards, p and q, in the top of which is hung the segmental pinion-shaft E. This shaft has also a bearing in the top of the axial post P. The vertical sleevej' is sustained by this post, which constitutes its axis. The sleeve is provided at the top with two segments of beveled gearing, G and G', of unequal diameter. It is also provided with a hollow arm, D, near its lowerl end, to receive the journal t" of the shank J of the raker-head M. The journal is secured to the arm by the bolt i, which is inserted through an openin g made in the under side of the arm and far enough from the end to give the necessary strength to that portion of the arm remaining outside of the piu when inserted. This pin z' also serves to hold the rakehead in its upper position while making its forward stroke. j

There is a spring-.locking latch or catch, b, pivoted to the arm D, as seen in Figs. 1, 2, and 3. This latch is kept in its proper adjustment by the spiral spring s. Near the lower end it is providedwith a hook or an opening, in which the pin fr' enters when the rake-head is raised, as shown in Fig. 2.

The pinious C and C are prevented from getting out of gear with G and G by means of the high tooth (shown at lL, Fig 2) on the rear edge of both segments. The toothed sections of the pinious C and G should be so graduated, with relation to each other and to the toothed wings G and G', that when one pinion is just going out of gear with its wing the other shall be entering-that is, both pinious shall never be entirely out of gear with the wings G and Gl at the same time. These pinions may be made of equal diameter, even when placed at unequal distances from the axialpost P, in which case the toothed segments G and G maybe made ou the same plane,instead of one being elevated above the other, as in the present case. If the pinions O and C are placed equidistant from the post I?, their toothed sections should be equal. It is desirable to give the rake a more rapid movement forward than when laboring or delivering the bundle. This is accomplished by reducing the diameter of segment G', which produces the return-stroke ot' the rake.

The shaft E is coupled to the shaft E by an ordinary universal or toggle joint, F. Shaft E is square at the upper end, and is fitted through a correspondinglyshaped mortisc in the ball g. This ball is fitted in a spherical Cavity formed within the hub (which is enlarged for that purpose) of the pulley B. This pulley is composed of two parts, which are secured together by screws or rivets n, as seen in Figs. 2 and 3. The hub projects on each side of the pulley, Yforming a cylindrical bearing in the yoke A, which is also composed of two parts, that are bolted to the machine, as seen in Fig. l, Sheet B. The ball g is provided with a spur or pin, lr, that takes in a lateral slot, o, formed in the pulley B, Fig. 3, for

this purpose, the slot allowing the ball to accommodate its position to that required by the ever-chan gin g direction of the shaft E, and that being fitted to slide through the ball permits the ordinary seliralrer to be used upon those machines having jointed eutter-bars.

Pulley B may be driven by a chain from the pulley X, hung loosely upon the ground-wheel shaft of the machine. This pulley is driven, when desired, by an ordinary sliding' clutch feathered tothe shaft, andit is operated by the driver. By pressing the footplate or spring` Y forward-in which position it may be retained by dropping the latch Z between it and the frameof the machina-the pulley X is thrown out of gear.

The plan for raising` the cutter-bar on the Ball machine is inconvenient for the driver to manipulate. Therefore I have arranged the elevating-lever L in a more accessible position than heretofore used on this machine. I hinge it to the front of the frame, so as to swing down between the inside driving-wheel and the end of the seat. It is held in any position toafford the desired elevation of the cuttechar, Src., by means of the ratchet O and projecting spurs or pins, c, which shall register to the openings e, whereby the pulley is effectually lockedl to the shaft when the parts are adjusted in the machine, and yet is easily applied or removed, and the pins drive the reel without twisting the journ al-pin xin the shaft B..

When the machine is being turned around the tongue is more or less elevated, which drops the, rear of the platform in a like proportion, and in consequence much injury is often produced to some portion of the inachine. To obviate this difficulty, I provide an inclined (forward) axis, J t0 the arm A of the caster-wheel W, Fig. 4, whereby, when the wheel is thrown forward, asV when backing or turning around, the platform is raised as much above its present position as the wheel W is indicated as below that of W.

Another serious objection to the ordinary construction of these machines has been that they left altogether too much con1b, and in short grain they would frequently pass over more or less grain at the divider without cu tting itat all,becauseitwould be pressed so obliquely from the line of the point of the divider D', Fig. l, to where the inner edge of the old dividers crosses the cutters (as indicated by the dotted line d) that more or less grain would be unavoidably drawn under the cut-ters without being gathered. I prevent all that by cutting away that portion of the dividers between the dotted line d and the inner face of the divider, as shown, which permits the grain to stand nearly straight or vertical, and cousequently there is scarcely any comb perceptible and no grain left uncut.

The operation of the ralrer is as follows: The pinions G and C are driven in the direction indicated by the arrow in. Fig. 2 by shaft E, always revolving in the same direction, and they gear alternately into the toothed wings G and GJ, thereby producing the reciprocating movements of the rake. As it is thrown back with a-bundle, and at the instant of delivering it, the lower end of the arm J strikes the cam I, which swings the rake lup inthe position' shown in Fig. 2, where it is caught and held by the spring-locking latch l) until the rake is swung forward again, when the tappet a presses the top of the spring-latch b back, so as to unhook the pin i, and the rake again drops or is forced to the position shown in Fig. 3 Iby the lower end of the shanlr J striking the cam K.

The shaft E may be made of round iron and feathered through the ball g, or grooved, and a pin inserted in the ball to work in the groove; but I prefer the square shaft, as shown.

The pins c may be cast on the pulley T, and corresponding recesses cast on the end of the sleeve S to receive them, if desired.

What I claim as my invention, and desire to secure by Letters Patent, is Y l. The sliding ralrer-shaftE, orits equivalent, and the joint-ball g, in combination with the drivii'lg-pulley'B, Lor other suitable case, when the latter has a cylindrical axis within the hanger A entirely independent of the said jointball g, as shown and described.

2. The arrangement, in4 combination with the sliding raker-shaft, of the ball g and the pulley B, or other suitable case, within the hanger A, the latter constituting cylindrical bearings for the axis of the said case or pulley B, as set forth.

3. The arrangement of the segments Gr and G upon the vertical sleeve f, and the segmental pinions C and C upon the horizontal driving-shaft E of the raker, as shown, so as to constitute collectively an entire circle of gearing, as shown and described.

4. The combination of the detachable pulley T with the sleeve or ferrule S, having one or more locking-pins, c, substantially as and for the purposes set forth.

5. The arrangement of the elevatinglever L, ratchet O', head Q, chain U, and pulley V, in combination with each other and the brace of the shoe, as and for the purpose set forth.
